using a Samsung, or the Crucial SSD that iFixIt sells?ģ) PCIe blade? From what I understand, the fusion drive is really comprised of a regular spinning SATA drive, and a 128GB PCIe flash drive, linked in the OS. OWC's upgrade kit seems to come with their own "Mercury Extreme Pro" SSD-thoughts on this vs.

I wonder if anybody can speak to the difference between them? I'm leaning towards iFixIt.Ģ) SSD model? What would you recommend? I've seen others mention a Samsung EVO to use for the HDD > SSD replacement. I've been reading the forums to get a sense of what this entails, but I have a few questions:ġ) Upgrade kit? I see that both iFixIt and OWC sell upgrade kits. I have a ~6 y/o 27" iMac (late-2014) that has a 1.12 TB fusion drive, which I'm looking to upgrade to a 1TB SSD.
